best thing for my site would be if yui RTE image upload works together with the drupal image module.
that way it would be possible to

- adjust the image size in the image module
- have an admin option for YUI RTE where we could opt for "Thumbnail", "Published" or other predefined sizes
- don't give the user the option to ruin a layout by using wrong image formats
- strip down the image upload box to the file box and nothing else
